Sakalava Weaver
Ploceus sakalava
Chunky, big-billed weaver of dry country. Yellow-hooded breeding male is distinctive. Both sexes have pink bare skin around the eye. Madagascar endemic that is found in the north and west at low and middle elevation. Preferred habitats include open forest, scrub, plantations, savannah, and villages. Very social weaver that is almost always found in flocks, sometimes mixed with other birds, and which nests in bustling colonies. The nest is a messy hanging orb. Song is a complex, high-pitched series of scolding and sizzling notes. Call is a husky “chert.” Female and non-breeding male similar to fodies, but separated by larger size, bigger bill, pink facial skin, and different facial pattern.

分类信息
The Sakalava weaver was first described by Gustav Hartlaub in 1861, based on a specimen collected by Victor Sganzin during an expedition in 1831–32 on Madagascar. The species epithet sakalava is derived from the Sakalava, whose name means 'people of the long valleys'. The first English name was given to the bird only in 1891 by James Sibree, who named it Sakalava Weaver-bird. Sakalava weaver has been designated the official name by the International Ornithological Committee (IOC). Another English name that is sometimes used is Sakalava Fody. Local names in the Malagasy language include fodibeotse, fodisahy, tsiaka, draky and zaky.<p>Based on recent DNA-analysis, the genus Ploceus is almost certainly polyphyletic. If all species currently included in the genus would remain and the genus would be made monophyletic, it would have to encompass the entire subfamily Ploceinae. The Ploceinae can be divided into two groups. In the first group, the widowbirds and bishops (genus Euplectes) are sister to a clade in which the genera Foudia and Quelea are closest relatives and which further includes the Asiatic species of Ploceus, i.e. P. manyar, P. philippinus, P. benghalensis, P. megarhynchus, (and P. hypoxanthus, although untested). Since Georges Cuvier picked P. philippinus as the type species, these five species would logically remain assigned to the genus Ploceus.<p>Basic to the second group is a clade consisting of both species sofar included in Ploceus that live on Madagascar, P. nelicourvi and P. sakalava, and these are morphologically very distinctive from the remaining species. These two species could in future be assigned to the genus Nelicurvius that was erected by Charles Lucien Bonaparte in 1850, but which was merged with Ploceus later on. This second group further contains the genera Malimbus and Anaplectes, and all remaining Ploceus species.

行为
Like in other true weaver birds, the roofed nest is woven from strips of grass leaf, but the Sakalava weaver also uses strips of palm frond or thatching and weaving materials collected in villages. The top is woven directly around a branch or attached from a short woven stalk. It is shaped like a retort, with a pear-shaped nesting chamber and a long entrance tunnel hanging from the top. The fabric is thin but dense, although less so with the tunnel, which may be slightly transparent and which may also be somewhat wider at both ends.

Karoo Bustard
Heterotetrax vigorsii
A medium-sized, drab, gray-brown bustard with a plain face and black throat patch. Creamy wing patches are displayed in flight. Small groups prefer semi-arid Karoo and barren farmland, where they feed on plants and small animals. During the heat of the day it retreats to drainage lines, where they shelter under thicker cover. Often first detected by its dry, throaty, frog-like two-or-three-syllabled “kraak-krook” or “kraak-krook-kook” calls, which are sometimes echoed by other group members, creating a choral cacophony. Vocal in the morning and late afternoon.
Sanford's White-eye
Zosterops lacertosus
A distinctive white-eye, mostly dark brown above and buff below. Note the large black beady eye with a broad pale eye-ring, the long yellow bill, and the yellow legs. Most common in primary forest, less common in secondary growth. Common call is a “chip” note. Seldom heard singing.
Cooper's Hawk
Astur cooperii
Small to medium-sized hawk with relatively short rounded wings and rounded tail. Adults are gray above with pale orange barring below; immatures are browner and streaky. Very similar to Sharp-shinned Hawk, but larger with bigger head. Also note deeper, slower wingbeats. Breeds in forested areas; more common in suburban areas than Sharp-shinned Hawk. Feeds mainly on birds captured in flight. Often stalks feeders in search of prey.
